The top horizontal surface of the toggle plate 51 pushes the groove wall of the toggle groove 9 upward, and the elastic belt 7 moves upward. The positioning column 16 is squeezed and rebounds into the inside of the circular groove 10. When the toggle plate 51 moves the next nail bullet 8 on the elastic belt 7 to the position of the through groove 6, the positioning column 16 will be stuck in the inside of the toggle groove 9 again to fix the position of the elastic belt 7, and the toggle plate 51 will be stuck in the toggle groove 9 again to realize automatic feeding.

[0026] As a preferred implementation in this embodiment, Figure 4 As shown, a first rack plate 53 is fixed at the middle position on one side of the connecting rod 52, a gear 54 is rotatably connected inside the clip 4, the gear 54 is meshed with the first rack plate 53, a second rack plate 55 is slidably fitted inside the clip 4, the second rack plate 55 is meshed with the gear 54, a pressing plate 58 is fixed on one side of the gear 54, the second rack plate 55 moves downward to drive the gear 54 to rotate, and then drives the first rack plate 53 to slide upward, and then drives the connecting rod 52 and the toggle plate 51 to slide vertically up and down.

[0027] As a preferred implementation in this embodiment, Figure 4 , 6 As shown, both side walls of the loading slot are provided with a first inner groove 11, and the interior of the magazine 4 is provided with a second inner groove 12, a third inner groove 13 and a receiving groove 14, the bullet feeding assembly 5 is installed on the inner sides of the first inner groove 11, the second inner groove 12, the third inner groove 13 and the receiving groove 14, the toggle plate 51 is slidably fitted inside the first inner groove 11, the gear 54 is rotatably connected in the receiving groove 14, the first rack plate 53 is slidably fitted inside the second inner groove 12, the second rack plate 55 is slidably fitted inside the third inner groove 13, a first spring 56 is fixed between the top of the first rack plate 53 and the groove top of the second inner groove 12, and the same first spring 56 is fixed between the bottom of the second rack plate 55 and the groove bottom of the third inner groove 13, when the second rack plate 55 and the first rack plate 53 slide in the third inner groove 13 and the second inner groove 12 respectively, the first spring 56 will be squeezed, and the elastic restoring force of the first spring 56 can drive the second rack plate 55 and the first rack plate 53 to automatically restore to the initial position.

[0028] As a preferred implementation in this embodiment, Figure 1 , 6 As shown, an extension plate 57 is fixed to one side of the second rack plate 55, and a clearance groove 15 is opened on one side of the magazine 4. The extension plate 57 passes through the clearance groove 15 and is fixedly connected to the pressing plate 58. The extension plate 57 slides in the clearance groove 15. Through the linkage of the extension plate 57, the second rack plate 55 can be driven to move downward by pressing the pressing plate 58.

[0029] As a preferred implementation in this embodiment, Figure 1 , 5 As shown in 7, a second spring 17 is fixed between one end of the positioning column 16 and the bottom of the circular groove 10, and the other end of the positioning column 16 is a spherical head. A gun chamber 3 is provided in the gun body 1, and a striker is installed in the gun chamber 3. By utilizing the elastic restoring force of the second spring 17, the positioning column 16 can automatically slide into the shifting groove 9 when not subjected to external force. The setting of the spherical head makes it easier for the shifting groove 9 to squeeze the positioning column 16.

[0030] Working principle:

[0031] The clip 4 is fixed inside the mounting groove 2, and the ammunition belt 7 is installed in the loading groove. The impact pin in the chamber 3 impacts the nail bullet 8, so that the nail bullet 8 is fired through the through groove 6. When the next nail bullet 8 needs to be fired, the pressing plate 58 is pressed downward to drive the second rack plate 55 to slide downward, and the second rack plate 55 drives the gear 54 to rotate. Under the transmission cooperation of the gear 54, the first rack plate 53 and the connecting rod 52 move upward first, and the top horizontal surface of the toggle plate 51 pushes the groove wall of the toggle groove 9 upward, and the ammunition belt 7 moves upward. The positioning column 16 is squeezed and rebounds into the inside of the circular groove 10. When the toggle plate 51 moves the next nail bullet 8 on the ammunition belt 7 to the position of the through groove 6, the positioning column 16 is under the action of the elastic restoring force of the second spring 17. When the toggle plate 51 is pressed down, it will be stuck in the inner part of the slot 9 again to fix the position of the elastic belt 7. At this time, the downward pressure of the pressing plate 58 is removed. Under the action of the elastic restoring force of the first spring 56, the second rack plate 55 slides upward to return to the initial position, and the first rack plate 53 drives the toggle plate 51 to slide downward to return to the initial position. The beveled surface of the lower surface of the toggle plate 51 is squeezed by the slot 9 and rotates outward and slides out of the slot 9. When the top end of the toggle plate 51 moves to the position of the next slot 9, the toggle plate 51 is stuck in the slot 9 again under the action of the torsion spring 59. The bullet feeding assembly 5 and the elastic belt 7 are connected in a coordinated manner. Repeatedly pressing the pressing plate 58 can send the nail bullets 8 on the elastic belt 7 into the inside of the through groove 6 one by one, so as to realize automatic, stable and continuous bullet feeding of the nail shooter.
